When you buy albums or songs on the Google Play Store, that music will be immediately added to your Google Play Music account as well as being available for download. If you're considering buying an album that isn't available for streaming in Google Play Music All Access, you may want to consider buying it on the Google Play Music Store. It's a free feature that allows you to access your music collection from anywhere. Better yet, this works even if you aren't paying for Google Play Music at all.
